Not for any specific reason, but just because I have always had a screw loose to begin with. I recently built my first mod, the Ugly Bug, which is a 5v 510 pass-thru that ended up in a big bulky harmonica case 4.5" x 1.5" x 1" because I melted my little flashlight original mod target. It works awesome though. I truly LOVE 5v modding and no battery to worry about now when sitting at the PC. So I have 4 tornado batteries sitting there fully charged all the time now. Nice..
AnyWho.. I ordered some parts to make my first 5v box mod. I am going to use dual 14500's for a 7.4v 1800mAh baby that I will regulate down to 5v of course. Unfortunately, I think I ordered the wrong regulator on MadVapes. I ordered the 5V 5A model, and it looks like it has a LDO of 6v!??! Yikes. Also, I am not sure but does this one require cap's and or resistors in order to specify the Vout ??? Hmmm..
I went ahead and jumped on TI and sent for some samples. I actually have a couple of regulators, some battery protection circuitry and a booster so that maybe I can make a 5v PV out of a single 14500 box? Well I have a question about the regulator I ordered as a sample.
It is the LP2950-50 Single Output LDO, 100mA, Fixed 5v. It is a 3 pin package and I am wondering if anyone else has used the 2950-50 in a mod before, if so, any advice for this regulator?
I hopefully will be able to make heads or tails out of the spec sheet and get it installed properly. It seems like a really nice regulator. A decent drop out of like 4v or so. Regulators are a fairly new thing to me, so I am still learning as far as they go. I actually don't remember working with them at all when I was in basic electronics assembly.
I am going to be using a 3AA battery box with a built in switch that will work for the master/kill switch, just going to add a second LED for the master indicator. If I get this regulator working, or if I end up ordering a 7805 or something else from MadVapes that will make better use of the extended mAh of the dual 14500's, well then I am going to work on developing a juice feed system. I will NOT use a bottom feed though. I use sealed battery connectors for a reason. I will not build a mod that will allow any juice to get inside. If I put on vents, they will be on the very bottom of the mod. So if I make a feeder system, it will have to be something different, and most likely external to the box. I have seen that one that involves putting a tube connected bottle in between the cart and atty, and I will look into something along those lines, except I think I will have the tube going straight into a cartridge and not having a third piece to add into the atty and cart. I already started drilling out old cartridges and turning them into cheap drip tips with my dremel. I can just punch a hole into the side bottom of one of those and use a thin tube and mister vial or something like that to spray a fine mist down into the atty, if that will work well.
I have now had my original atty still functioning after 2 months (knocks on wood) and the key is, just like I read several times, keep your atty wet and it will live. I do a very basic and quick cleaning of it every few days or so. I just drop it in very hot water for a minut, then I literally blow into both ends and dunk again, and I keep repeating this until nothing comes out but clear liquid, then I stop the dunking and just keep blowing air through the atty until the water stops coming out, and then I use it. I have had no issues with this so far, and this also seems to eliminate any funky smells and tastes that have started happening on my 2 month old atty a few times. So I have no issues with using a drip tip and if I can turn my drip tip into a juice misting drip tip on my 5v box, I think I will be a pretty happy camper.
The only thing standing in my way right now will be seeing what works out with the regulators. So anyone have any information or advice on any of these regulators for me? Would be appreciated.
